client_cmd spk

Hello, iam trying to play specific sound with specific volume using client_cmd "spk" to avoid 512 limit but i get this error in the folowing code

>> error 017: undefined symbol "s" <<

specificly on this line

>> client_cmd(iPlayer, "spk \"%s^%.2f\"", SOUND_MESSAGE, volume); <<

here is the code:

stock UTIL_PlaySpeakSound(iEmmiter, const SOUND_MESSAGE[])

{

new Float:origin[3], Float:clientPos[3], Float:distance, Float:volume;

pev(iEmmiter, pev_origin, origin);



for (new iPlayer = 1; iPlayer <= get_maxplayers(); ++iPlayer)

{

if (!is_user_connected(iPlayer))

continue;



pev(iPlayer, pev_origin, clientPos);

distance = vector_distance(origin, clientPos);



if (distance <= MAX_DISTANCE_SQR)

{

// Calculate volume based on distance

volume = 1.0 - (floatsqroot(distance) / floatsqroot(MAX_DISTANCE_SQR));



// Clamp volume within specified range

volume = floatclamp(volume, MIN_VOLUME, MAX_VOLUME);



// Send message with volume to client

client_cmd(iPlayer, "spk \"%s^%.2f\"", SOUND_MESSAGE, volume);

//client_cmd(iPlayer, "spk ^"%s^"", SOUND_MESSAGE);

}

}

}
